We used a modified MTT assay to assess the impact of RRM1 expression on therapeutic efficacy of gemcitabine and platinum analogs in vitro. H23, originating from a lung adenocarcinoma, was used as the parent cell line.27 H23-R1 had a 2.5- to 3.5-fold increased RRM1 expression compared with H23.22 H23siR1 had a five-fold reduced RRM1 expression. The expression levels of RRM1 and control genes were determined by real-time quantitative RT-PCR and Western blotting. The expression of RRM2, the catalytic ribonucleotide reductase subunit, was unaffected. The sensitivity of these cell lines to gemcitabine, cisplatin, and carboplatin was compared with transfected control cell lines H23-Ct and H23siCt ; . The results are summarized in Table 1. Increased RRM1 expression resulted in resistance to gemcitabine Fig 1 ; . The gemcitabine IC50 of H23-R1 was eight-fold higher than the IC50 of H23-Ct. Reduced RRM1 expression increased sensitivity to.
Low-Dose Oral Contraceptives and Acquired Resistance to Activated Protein C: A Randomised Cross-Over Study--Rosing J Dept of Biochemistry, Cardiovascular Research Institute Maastricht, Maastricht Univ, PO Box 616, 6200 MD Maastricht, Netherlands ; , Middeldorp S, Curvers J, Thomassen MCLGD, Nicolaes GAF, Meijers JCM, Bouma BN, Bu ller HR, Prins MH, Tans G--Lancet. 1999; 354: 2036 Background We have reported previously that, compared with use of second-generation oral contraceptives, the use of third-generation oral contraceptives is associated with increased resistance to the anticoagulant action of activated protein C APC ; . Owing to the cross-sectional design of that study, these observations may have been subject to unknown bias or uncontrolled effects of the menstrual cycle. We aimed to overcome these sources of bias by doing a cycle-controlled randomised cross-over trial.

Rigas, Dragnev first-line chemotherapy [72]. A total of 52 patients who had demonstrated stable or responsive disease after prior chemotherapy were eligible for the trial. Fifty-two percent had achieved an objective response and 48% had achieved stable disease in response to prior chemotherapy. The majority 69% ; of these patients had received prior paclitaxel carboplatin chemotherapy. Patients were randomized to bexarotene 300 mg m2 day, bexarotene 600 mg m2 day, or placebo. The median TTP increased from 8 weeks for patients treated with placebo to 11.7 weeks for patients treated with bexarotene 300 mg m2 day. This increase in TTP appeared to be dose dependent, with the TTP in patients treated with 600 mg m2 day increased to 18.3 weeks. However, this trial was prematurely terminated because of slow accrual and, therefore, was insufficiently powered to detect statistical differences among the treatment groups. Nevertheless, these results are suggestive of a benefit for bexarotene over placebo in maintenance therapy. Dose-dependent hyperlipidemia was the only grade 3 4 toxicity associated with bexarotene therapy reported in more than three patients, with the exception of decreased absolute lymphocyte count. However, grade 3 4 absolute lymphocyte counts were as common in the placebo group as in the bexarotene-treated groups. Thyroid-stimulating hormone TSH ; levels 75% of normal were noted in 58% of patients receiving bexarotene. Dose-dependent dry skin, headache, and asthenia were the most common bexarotene-related toxicities. However, these were mild to moderate and were manageable. Current Phase III Trials Enrollment in two phase III trials has recently been completed to investigate the efficacy and safety of bexarotene in combination with chemotherapy in previously untreated patients with stage IIIB with malignant pleural effusion ; or stage IV NSCLC. In the first randomized, open-label, parallel-group controlled trial in patients with advanced NSCLC, the regimen is paclitaxel 200 mg m2 via a 3-hour i.v. infusion on day 1 every 3 weeks followed by carboplatin AUC equal to 6 by i.v. infusion every 3 weeks, with or without oral bexarotene 400 mg m2 once daily starting on day 1. All patients treated with bexarotene also receive antilipid therapy concomitantly or on the same day of bexarotene therapy. In the second trial, chemotherapynave patients with advanced NSCLC receive cisplatin 100 mg m2 by i.v. infusion on day 1 of a 4-week cycle and weekly vinorelbine 25 mg m2 by i.v. infusion, with or without oral bexarotene 400 mg m2 day. Similar to the other phase III trial, patients receiving bexarotene are initiating antilipid therapy before or on the study drug start date. Both studies are ongoing as the primary efficacy parameter is survival.
PATIENT ELIGIBILITY Eligiblily criteria were: histologically proven unresectable gastric adenocarcinoma that progressed or recurred after treatment with 5-FU plus platinum agents, cisplatin or heptaplatin, used in an adjuvant setting or to treat metastatic disease. Each patient was required to have at least one measurable target lesion with at least one diameter 2 cm on computed tomographic CT ; scan, or 1 cm as determined by physical examination. Ages had to be within the range of 1870 years and each patient had to have an Eastern Cooperative Oncology Group ECOG ; performance status of 2 or better with adequate hematological [white blood cell count 4 109 l, absolute neutrophil count ANC ; 1.5 109 l and platelet count 100 109 l], renal serum creatinine level 1.5 mg dl ; and hepatic function serum bilirubin level 1.5 mg dl, transaminase levels 3 times normal, or 5 times normal for patients with liver metastases ; . Patients had to receive no chemotherapy treatment for at least 4 weeks, and no radiation therapy for at least 3 weeks, prior to enrollment. Patients were ineligible if they had been previously exposed to taxanes or carboplatin or had co-existing malignant diseases at other sites, symptomatic central nervous system metastases, or other diseases for which systemic chemotherapy was contraindicated. The protocol was approved by the ethics and human investigation committee of the institute. Written informed consent was obtained from each patient before entry into the study and carmustine.

Former is instantiated once and represents the black-boxed kernel. An instance of the latter component type exists for each driver. Each driver is verified separately. In the time of verification, other drivers are seen as a part of environment and details of their interior are also not visible to the verifier. To be correct, each driver should only rely on the specifications of the kernel component as defined by DDK. In rare cases there may be a library loaded to the kernel so called export driver ; which behavior is well-defined and which is designed to be used by multiple drivers. In such a case, a specification of the library should be known and the library itself can then be viewed as a part of the kernel component. Since this situation is rare, it is not discussed any more in the thesis. The driver can expect no goodness coming from other drivers, i.e. it can receive any input anytime from them. The drivers not being checked in the moment can also interact with the driver being checked through the kernel. Such an interaction is then partially described by kernel specification and partially undefined. For the purpose of verification, data passed between drivers via kernel are randomized within the bounds of the kernel specification. The driver should make all checks necessary to discover incorrect inputs. The aim of the verification is, among others, to verify whether the driver does all such checks. Due to this clear separation of the driver being verified and the around environment, it is possible to model the driver using its source code and the specification of the interfaces provided and required by the environment. Neither the kernel's nor 3rd party driver's source codes are necessary for the verification.
72. THALIDOMIDE AND CARBOPLATIN IN THE TREATMENT OF BRAIN STEM GLIOMA Goldman S, Tomita T, Marymont M, Kalapurakal J, Carlson A, Bendel A, Hyder D, Etzel M, Cohen K; Division of Oncology, Children's Memorial Hospital, Chicago, IL, USA Brain stem gliomas account for approximately 10% of pediatric CNS tumors. Multiple clinical trials of radiation with standard cytotoxic regimens have failed to increase survival. This protocol incorporates an antiangiogenic agent thalidomide ; with carboplatin and radiation therapy to increase PFS. Materials and Methods: Fourteen patients with pontine gliomas age 4.2 to 19.8 years mean 7.6 yrs ; were treated on a protocol that included Carboplatin and thalidomide. Ten patients were treated at diagnosis; 4 were treated after progression. The newly diagnosed patients received 5460 Gy irradiation concurrent with this regimen. Nine females and 5 males 9 Caucasian, 4 Hispanic, and 1 Native American ; were enrolled. The lesions were intrinsic in 13, with 1 patient having a partially extrinsic tumor. Carboplatin was administered at a dose of 560mg m2; thalidomide is dosed at 300 mg m2 escalating to 700mg m2 daily. Results: Best response data for 12 evaluable pts: 5PR, 4SD, 3PD; patients with SD had neurologic deterioration with stable MRI but were coded as PD due to clinical deterioration. Mean time to progression was 194 days range 22537 days 3 pts remain PFS at 100 + , 288 + , 358 + days. Mean TTP for 8 evaluable pts treated at diagnosis was 288 days 3 pts remain PFS the mean TTP for the 4 pts treated following progression was 48 days. Two patients progressed with disseminated disease, without evidence of increase in tumor in the pons. Toxicities include gram negative bacteremia 1 ; , rash 3 ; , Stevens-Johnson syndrome leading to withdrawal from study 1 ; , pulmonary emboli 1 ; . Constipation was seen in most patients but well controlled with prophylactic regimens. Somnolence was easily controlled with titration of dosing. Conclusion: This regimen is feasible and well tolerated. This protocol in the treatment of newly diagnosed pediatric brain stem gliomas, appears promising. This study continues to accrue patients and further follow-up is warranted and carteolol.

Group 2. Indeed, septal lines were not only more frequently present but were also more abundant in patients in group 1. A vasculopathy affecting capillaries and veins pulmonary veno-occlusive disease or pulmonary capillary hemangiomatosis ; was found in the six patients in group 1 who underwent postmortem examination of the lung. These vasculopathies are rare entities that have many pathologic similarities and may in fact overlap 4 hence, we did not separate these two entities in evaluating our results. The characteristic anatomic abnormality in pulmonary veno-occlusive disease is obstruction of the pulmonary veins and venules by intimal fibrosis, cellular proliferation, and muscularization 14, 20 ; . Pulmonary capillary hemangiomatosis is characterized by a proliferation of small blood vessels within the peribronchovascular, septal, or pleural connective tissue. The infiltration and compression of pulmonary veins by these neocapillaries can result in a secondary pulmonary venoocclusive disease 4, 21, 22 ; . To our knowledge, few reports have been published about CT and thin-section CT findings in pulmonary veno-occlusive disease or pulmonary capillary hemangiomatosis. The most common CT findings that have been reported are very similar to the CT findings in our study interlobular septal thickening, poorly defined nodular opacities, pleural effusions, and lymph nodes ; 4, 1419 ; . To our knowledge, no other disease process would be expected to consistently produce this constellation of thinsection CT findings. These findings are unusual in primary pulmonary hypertension. Some reports have described similar findings in cases of pulmonary hypertension, but these findings are usually secondary to a well-established cause such as chronic thromboembolic disease. Several studies have revealed the presence of ground-glass opacities in patients with pulmonary hypertension of different causes 23, 24 ; . Ground-glass opacities were identified substantially more often in patients with chronic thromboembolic pulmonary hypertension than in patients with primary pulmonary hypertension 12 ; . Furthermore, these reports generally described a mosaic pattern of lung attenuation, not the poorly defined nodular opacities of class I ground-glass opacity found in our study. Another report described the presence of centrilobular nodules in patients with pulmonary hypertension, but these findings were isolated ie, no septal lines, adenopathy, or pleural or pericardial effusions were present ; 25 ; .

The investigation of new drugs in a curable tumour places great responsibility on the oncologist to be particularly rigorous in ascertaining efficacy. The story of the evaluation of carboplatin in germ cell tumours emphasises the importance of a good prospective randomised trial design in the provision of secure evidence of efficacy equivalent to that of cisplatin. At the time carboplatin became available for investigation in germ cell tumours, the standard chemotherapy in these tumours in most centres was based on the combination of cisplatin, etoposide and bleomycin [1]. Prognostic factor analysis had allowed definition of a particularly good prognosis subgroup of patients with metastatic disease with a survival probability of more than 90% [2-4]. In those patients clinical trials were designed to develop regimens of reduced toxicity and included evaluations of the need for bleomycin [5] in order to avoid lung toxicity, as well as evaluations of carboplatin to avoid the renal toxicity, neuro-toxicity and ototoxicity risks of cisplatin [6]. Additionally because intensive i.v. fluid hydration is unnecessary, the administration of carboplatin is a simple outpatients procedure. The pharmacokinetics of carboplatin differ from cisplatin. It is less extensively protein-bound [7], has a longer plasma half-life and a larger percentage is excreted via the kidneys [8]. Pharmacological studies have suggested that in vivo biological effects of a dose of this drug are determined by renal function [9]. The major pilot study of carboplatin in the combination chemotherapy of germ cell tumours was carried out in the Royal Marsden Hospital between 1984 and 1989 and involved the chemotherapy of patients with good prognosis metastatic non-seminomatous germ cell tumours treated with 4 cycles of the combination of carboplatin, etoposide and bleomycin CEB ; . Bleomycin was administered at 30 U i.v. per week for 12 weeks. Etoposide was given intravenously at a dose of 120 mg m2 per day on days 1 to 3 inclusive of each of 4 cycles with cycles repeated every 21 days. The dosage of carboplatin was initially based on body surface area in a dose escalation study ranging between 300 mg m2 and 450 mg m2. However, following pharmacological studies confirming the accuracy of predicting the serum concentration x time [10], the carboplatin dose was calculated to achieve a serum concentration x time AUC ; of 4.6 mg ml x min in 20 patients and subsequently an AUC of 5 mg ml x min in 75 patients [11, 12]. With a median follow-up of 40 months from the start of chemotherapy, 118 of 121 patients remained alive and no patients had died from progressive germ cell tumour. One death was from ischaemic heart disease 3 years following chemotherapy, 1 from haemorrhage following replacement of aortic graft 6 years following chemotherapy and 1 from bleomycin pneumonia's. Nine patients were considered to have failed CEB chemotherapy of whom 5 had undifferentiated tumour resected following chemotherapy and a further 4 relapsed following apparent complete clinical remission. The study permitted comparison of the relationship between carboplatin dose and toxicity, comparing a dose based on body surface area and a dose given to achieve a particular serum concentration x time deriving from the glomerular filtration rate. At a carboplatin dose of 400 mg m2 or greater, 2 of 58 patients 3.4% ; failed treatment, while 7 out 63 patients 11% ; treated as a lower carboplatin dose than this failed P 0.1 ; . At an AUC of 5 mg ml x min or greater, 2 of 74 patients 2.7% ; failed, while 7 out 47 patients 40.9% ; who had an AUC less than this failed P 0.05 ; . The failure rate rose to 26% for doses 4.5 mg ml x min and in view of the more precise determination of toxicity and efficacy it was recommended that carboplatin dose be based on careful measurement of the glomerular filtration rate and that further evaluation of the combination be undertaken at a carboplatin dose to achieve a serum concentration x time of 5 mg ml x min using the formula derived from Calvert et al. 1989 ; [9]. Dose-AUC GFR + 25 ; where the dose was in mg and GFR in ml min. Despite the excellent results achieved in this singlecentre pilot study, there have now been reports from two substantial prospective randomised trials indicating that in the chemotherapy of good prognosis germ cell tumours, carboplatin combinations were inferior to those based on cisplatin. The first trial to be reported was based on 270 patients treated between October 1986 and December 1990 and was mainly a collaboration between the Memorial Sloan-Kettering Cancer Centre and the Southwestern Oncology Group. The patients were randomised to receive 4 cycles of either etoposide cisplatin EP ; or etoposide carboplatin EC ; . The etoposide dose in all patients was 100 mg m2 per day on days 1 through 5. EP patients received cisplatin 20 mg m2 per day on days 1 through 5 and chemotherapy was recycled at 21-day intervals. For patients receiving EC the carboplatin dose was 350 mg m2 in the first 17 patients, 400 mg m2 in the next 5 patients and 500 mg m2 in the remaining 108 patients and the and cefprozil.

Direct consequence of IP treatment, but rather a result of the two initial IV carboplatin treatments, which was designed to minimize the residual volume of disease prior to IP treatment.23 Finally, another phase III trial was generated to evaluate the addition of IP paclitaxel based on its safety profile and pharmacokinetic properties. Patients with newly diagnosed optimal stage III disease were randomized to receive either IV paclitaxel and cisplatin or IV paclitaxel, IP cisplatin, and IP paclitaxel.24 The preliminary data indicated improvement in progression-free survival but greater toxicity with the IP paclitaxel regimen. Optimal regimens for IP therapy, including those utilizing IP carboplatin, continue to be defined through on-going clinical trials
Leibniz Institute for Solid State and Materials Research Dresden, PF 27 01 16 D-01171 Dresden * Department of Urology, Technical University of Dresden, Fetscherstrae 74 D-01307 Dresden + The application of carbon nanostructures as potential drug delivery systems has been discussed thoroughly in the last years[1, 2]. Due to their mechanically and chemically stable shell structure, biofunctionalizability and the advantage since they provide a smart carrier system in the nanometer scale carbon nanotubes CNTs ; are considered to be qualified drug deliverers. Biocompatible nanocontainers open a wide potential of applications by filling them with different materials. In order to functionalize CNTs as therapeutically active units they are filled with suitable drugs. In the contemporary chemo therapy platinum analogues are common anticancer agents. This group of cytostatic drugs comprises six complexes amongst which Cisplatin was the first to be explored and is since the most frequently used one. But its further development Carboplatin is more water soluble and less toxic. To pave the way for an intrinsic chemo therapy using carbon nanotubes the feasibility of loading multi walled carbon nanotubes MWCNTs ; with Carboplatin has been tested in this study. The filling is carried out by a liquid phase method in which opened MWCNTs are stirred in an isotonic Carboplatin solution. Applying electron microscopy the Carboplatin is observable as spherical clusters which are found mostly inside the tubes. The amount of Carboplatin associated with the MWCNTs rises with increasing concentration of the Carboplatin solution and the reaction temperature. Identity of Carboplatin was affirmed by energy-dispersive X-ray spectroscopy EDX ; , electron energy loss spectroscopy EELS ; and X-ray Photoelectron Spectroscopy XPS ; . Results of in vitro studies verified the virtue of the therapeutic loaded CNTs. Therefore bladder cancer cells cell line EJ28 ; were treated with the Carboplatin filled MWCNTs for 24 hours. 24, 48 and 72 hours after start of the treatment a WST-test a colorimetric assay based on the reduction of a tetrazolium salt ; was performed to measure the viability of the cells. It was proved that the Carboplatin filled MWCNTs exhibit anticancer effects and therefore are of potential for drug delivery. [1] A. Bianco, K. Kostarelos, M. Prato.

The presence of residual leukemic cells was studied using metaphase-fluorescence in situ hybridization FISH ; in 22 patients with acute myeloid leukemia treated with chemotherapy only or chemotherapy followed by allogeneic bone marrow transplantation. The patients were followed up during their complete remission CR ; for 4 to 108 months median, 21 months ; . A total of 88 BM samples was studied. In most of the samples more than 1, 000 metaphase cells were analyzed. Residual leukemic cells were detected in 9 of patients 41% ; . All patients who had an increasing and or persisting level of abnormal cells in two or more subsequent samples or whose initial samples contained more than 1% of abnormal cells relapsed with one exception, in whom the later subsequent samples showed disappearance of abnormal cells. The time span before the first positive sample seems to be insignificant with regard to the outcome of relapse. Absence or single occurrence of abnormal cells followed by their disappearance was in agreement with CR in all the cases 16 patients ; . Our results indicate that metaphase-FISH is a reliable tool in the quantitation of residual leukemic cells and provides valuable prognostic information for patients with AML. 1997 by The American Society of Hematology and carboplatin.
All patients received unmanipulated T-cell replete HLA-matched at A, B, and DR ; bone marrow n 147 ; or peripheral blood n 20 ; grafts and standard immunosuppression prophylaxis. We excluded HLA-mismatched transplants to avoid obscuring a relationship between HLA DR15 and transplant outcomes by the powerful alloimmune response generated and the use of higher doses of IST in HLA-mismatched transplants. Second or greater transplants were excluded, as were patients with ALL and other diagnoses. Institutional review board approval was obtained at Roswell Park Cancer Institute to conduct this review of existing data and all individual patient data have been deidentified and celestone.

Al., 2003 ; . Fifty-four patients with a median age of 60 years were accrued, 52% of whom were female. Eighty-five percent of patients had tumors that stained 3 + for EGFR. Response rate, the primary endpoint, was 27%. Median survival was 7.5 months, and the 1year survival rate was 38%. Grade 3 to 4 rash occurred in 20% of patients and grade 3 to 4 fatigue occurred in 19%. Based on these results, an ongoing phase III trial evaluating either docetaxel or pemetrexed alone or in combination with cetuximab is underway. Cetuximab has also been assessed in treatment-nave patients in combination with either gemcitabine carboplatin or paclitaxel carboplatin Kelly et al., 2003; Robert et al., 2003 ; . The demographic and response data are shown in Tables 1 and 2. In each of these studies, grade 3 to 4 follicular rash occurred in 10% to 20% of patients, but hypersensitivity reactions occurred in fewer than 3%. There was no obvious exacerbation of nonhematologic toxicities by cetuximab. Response rates and survival data are promising. Finally, in Europe, a randomized phase II trial of cisplatin and vinorelbine + - cetuximab was performed Rosell et al., 2004 ; . Median survival was 8.3 months in the cetuximab regimen, compared to 7.0 months in the reference control, with 1-year survival rates of 32% and 26%, respectively, and 2-year survival rates of 14% and 0%, respectively. Patients receiving cetuximab had a higher incidence of asthenia, fatigue, fevers, chills, skin reactions, and hypersensitivity reactions. These observations have set the stage for a phase III trial, which is underway and carmustine.
